Computer generated shapes patterns and hallucinations. This time Transhypnagogia was debugged to handle grayscale images properly. The computer got various pictures for inspiration and tried to mimic their structure. The depth of understanding is varied during each clip, which produces patterns of changing style. These original images were ball bearings, computer game, photograph of landscape, photograph of crowd, photograph of bodybuilders. Soundtrack - paniq: preselected. Source code of the...

Ronja is a DIY project of optical wireless datalink hardware. Karel Kulhavy of Twibright Labs, creator of the project, held a talk about Ronja on WSFII (World Summits on Free Information Infrastructures) in London in 2005. This is the complete recording of the talk, cleaned up (ummmm....ummmm.... edited out, otherwise unabridged) Topics: Ronja, Twibright, datalink, data link, optical, wireless, talk, WSFII, London, DIY, user controlled...
Do androids dream of electric sheep? Computers can dream of dogs, frogs, juggling centipede rabbits, lamas, groups of snowman children, angry faces, cats, ostriches, galloping horses and other shapes. A simple algorithm takes a visual input - in this case an excerpt from Voynich Manuscript http://en.wikipedia.org/wiki/File:Voynich.png - and tries to randomly assemble elementary forms encountered in the input.

Twibright Exciter is an open source product of pedal power generator at http://ronja.twibright.com/exciter/In this video we hack it into a series mode and using thick electrician insulating gloves, thick insulated wires and other safety measures, we are making arcs. In this hacked mode Exciter produces over a kilovolt ignition spikes. But normally Exciter is perfectly safe and contains a reliable voltage limiter for 350V DC, which allows it to power ordinary switched mode appliances like mobile...
